The first trailer for Bleecker Street’s Captain Fantastic has dropped online today, and it’s looking like the film is as odd and interesting as its premise. Starring Viggo Mortensen, the Sundance film follows a father raising his six children in the forests of the Pacific Northwest on a rigorous physical and intellectual education. Forced to leave his home and enter the world, he begins a journey that challenges his idea of what it means to be a parent. It’s not hard to imagine a lazier, alternate version of this concept that sees Mortensen as a kind of dangerous cult leader. Fortunately, as seen in the trailer, he’s simply a difficult, idealistic man and devoted father whose values are at odds with modern culture rather than an evil rejection of it. See for yourself below.

From actor-turned-writer/director Matt Ross, the film also stars Frank Langella, George MacKay, Kathryn Hahn, Steve Zahn, Ann Dowd, Samantha Isler, Annalise Basso, Nicholas Hamilton, Charlie Shotwell, and Shree Crooks. It was produced by Lynette Howell Taylor, Jamie Patricof, Shivani Rawat and Monica Levinson. Captain Fantastic is playing the Cannes Film Festival and then hits U.S. theaters July 8.
